Thomas' agent Lamont Smith announced that Thomas has agreed to terms with the San Francisco 49ers. Thomas will essentially replace Reggie Bush as a passing-down back after Bush was lost for the season with a knee injury.

The Niners later confirmed Thomas' signing in a release. Bush was officially placed on injured reserve in a corresponding move.

Thomas averaged 8.4 yards per catch last season and 4.9 yards per carry on 45 carries for the Saints. He's been one of the more underrated role-playing running backs of the last decade and specializes in the screen game. With Blaine Gabbert taking over at quarterback in San Francisco, look for the 49ers to build in as many "safe" throws in the offense as possible.

With starter Carlos Hyde recovering from a foot injury, Thomas could be asked to do more than just handle third-down work for a little while.
